CASTER.

SPECIFICATION forming part of Letters Patent No. 898,641, dated February 26, 1889.

Application filed April 14:, 1888. Serial No. 270,685. (No modeld To all whom, i/; may concern: I

Be it known that I, SIcIsMUND )l. )IICHEL- SON, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Safe, Stove, and Heavy Furniture Casters; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to safe, stove, and heavy furniture casters; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter, and pointed out 1 in the claim.

In the drawings, l igure l is a vertical sectional View of one form of my improved device on the line 1. l of Fig. Fig. 2 is a similar view, but taken on a line at practically rightangles to that on which Fig. 1 was taken. Fig. 3 is a plan view of this device. Fig. i is an under side view of my device detached from 1 the housing. Fig. 5 is a side view of a some- 1 what modified construction of said detached part. Fig. 6 is a vertical sectional view taken on the same line as Fig. 2, but illustrating another form of my present invention: and Fig. 7 illustrates another modification.

A represents the part of the stove, safe, or other heavy article to which my device is to be attached, as shown; and 13 B (l represent upwardly-extending flanges, and D a horizontally-extendin g flan ge, of the housing E, which latter is provided with an opening, a, in its bottom plate, to admit of the passage therethrough and movement of the roller F, while around this opening on the upper surface of Y the said bottom plate is a circular track or rail, I), to receive the travel of a small antifriction roller, 0, suitably journaled in or at i the end of the long arm d of the frame G, l which frame has downward. extensions 6 e for supporting the axlefof the main or tloor roller 1 F, while said frame is continued beyond this point, terminating in ashort arm, 9, which extends over the said track, but without coming in contact therewith when the roller F is I on the floor;but if the article is lifted, so that said. roller F is free from the floor, then this short arm g rests on said track and prevents the frame from dropping out through the opening a in the bottom plate of the housing.

The roller-axle 1" may be secured to the frame-extensions cc in any suitable way; but

' I prefer the construction illustrated, which shows the adjacent inner faces of said extensions recessed at their lower edges to receive said axle, (which is made short for this purpose,) and provided with tongues 71. 71, which are bent or struck around under said axle, securing it in place, as best shown in Figs. 1, l, and 5. The housing E is also recessed, shown at i '1' in Figs. and (i, to receive the ends of a bar, 11, and this bar and the frame it are provided one with a conical bearing, j, and the other with a corresponding depres sion or socket, 71:, (it being immaterial which part has the bearingmint and which the socket, as shown by Figs. 2 and t3, respectively,) and when the device is all put together, as shown, no other securing device is needed to hold the parts in operative position, thereby doing away with the expense, trouble, and liability to breakage attending the use of pivot-bolts or rivets, as is common in devices of this class.

As stated, the anti-friction roller 0 is suitably journaled in or at the end of the long arm (I of the frame G, and this may be done by forming the end of said arm with the downward extensions m. m and supporting the roller 0 between them on an axle, n, as shown in So 1. and l, (the ends of this axle being preferably upset;) or the end of the said arm d may be rounded into an. axle beyond ashoulder or collar, 0, formed on said arm, and

then, after the roller cis in place on said axle 8 5 end, a ring or washer, p, may be slipped next it, and the extreme projecting end of the arm (Z may then be upset, all as shown in Fig. 5.

\Vhile I show the part II in the upper part of the housing as a bar, and so describe it, I go do not wish to be understood as limiting myself thereto, as instead of a bar I may use a plate covering all, or nearly all, of the well or space in the housin or the said bar or plate may be solidly castwith or rigidly secured to 9 5 said housing, if preferred.

As shown in Fig. 7, there may be a plurality of arms 9, to prevent the frame G from dropping out when the article to which the caster is attached is lifted. 10o

having a suitable track or bearingsurfaee for engagement with the said anti-friction roller, substantially as set forth;

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of VVisconsin, in the presence of two Witnesses.

SIGISMUND M. MICHELSON.
